P03-17 Evaluation of an asset-based, participatory physical activity promotion intervention in Dutch adolescents: a parallel group randomized trial

Abstract Background Adolescents tend to be less physically active and thus become more vulnerable to health risks. Engaging adolescents becoming agents of their active lifestyle could potentially catalyze the impact of interventions. Therefore, the effects of an asset-based physical activity promotion intervention on the physical activity behavior and physical fitness of pre-vocational students was evaluated, taking into account the extent to which the students were involved in the design and implementation of the interventions. Methods This randomized controlled trial included 2286 prevocational students divided between an intervention and control group. Innovative triple-i interactive research methods were used to develop and implement tailor-made interventions in co-creation with students and teachers. Self- reported physical activity behavior and direct assessments of physical fitness levels were determined on baseline and two annual follow-ups. Student involvement was determined by validated questionnaires. Generalized estimating equations were performed to determine intervention effects over time. Sensitivity analyses were conducted to evaluate the effects of the extent of student involvement. Results No intervention effects were found for total physical activity level, screen time, active transport and sports activities (CI includes zero; p > 0.05). Positive effects of the intervention were found for the long jump (β = 3.44; CI = 1.29:5.58; p = 0.01), the handgrip strength (β = 0.55; CI = 0.02:1,08; p = 0.04), the shuttle run test (β = 0.28; CI = 0.02:0.54; p = 0.03) and the sum of skinfolds (β=-0.08; CI=-0.11:-0.06; p = 0.01). Subgroup analyses on the extent of student involvement showed mixed results. Students at intervention schools where students involvement was more successful showed no alterations in physical activity levels and higher scores on shuttle run scores (β = 0.58;CI=0.29:0.87; p = 0.00) compared to controls. Students at intervention schools that were less involved, showed higher scores on long jump (β = 7.77; CI = 4.78:10.76; p = 0.00), grip strength (β = 1.34; CI = 0.61:2.06; p = 0.00), and sum of skinfolds (β=-0.15; CI=-0.19:-0.10; p = 0.00). Conclusions The participatory physical activity intervention in this study does not change physical activity level but does improve some elements of physical fitness. The research methods used in this study offers a protocol to align intervention plans to the students' assets by co-creation which is feasible to use in the school context.


Background
Physical activity (PA) is an important factor contributing to general health. PA declines rapidly during tween years (9-12 years) when children's social world changes. During tween years, children's self-consciousness develops and their focus on social status, friendships, and appearance increase. It is therefore important to consider how to motivate tween's to be physically active. School playgrounds can contribute substantially to children's PA and are considered key contexts for children to be physically and socially active. Despite the potential of school playgrounds, little is known about how to motivate tweens to use school playgrounds. Use of motivational theories in health research has increased rapidly in the last 20 years and the Self-Determination Theory has been used to conceptualize and analyze motivation. Using the three basic psychological needs (autonomy, competence, and relatedness) proposed by the Self-Determination Theory, this qualitative study aimed to investigate how school playgrounds can support tweens to enhance their autonomous motivation for PA on school playgrounds.

Methods
We interviewed 56 tweens in focus group go-along interviews in their school playground.

Results
We found that playgrounds could support each of the three basic psychological needs. School playgrounds supported the need for autonomy when the tweens could freely choose from different play equipment pieces. Furthermore, playgrounds should provide enough space to avoid noisy areas and congestion. To support competence, playgrounds should facilitate challenges at different levels, enabling the tweens to practice and experience task mastery. These challenges should contain an element of risk where the tweens can experience a high degree of competence. Playgrounds provide a unique possibility for making and strengthening social bonds. To support relatedness, playgrounds should include areas to hang out and talk with friends of a similar age.

Conclusion
This research highlighted the importance of incorporating tweens' perspectives in playground design to attract and retain Abstract citation ID: ckac095.053 P03-17 Evaluation of an asset-based, participatory physical activity promotion intervention in Dutch adolescents: a parallel group randomized trial Background Adolescents tend to be less physically active and thus become more vulnerable to health risks.

Background
Among adolescents there is a notable decline in physical activity (PA) levels from childhood, more notable among females than males. Visibility is regularly a cornerstone of strategy to promote engagement with women's sport particularly around stimulating and sustaining female participation in sport and PA. This includes leveraging sporting role models (SRM) to develop participation in sport and PA. The purpose of this research is to locate and describe the features and impact of SRM led interventions on female participation in sport and PA. Methods APA PsychInfo, PudMed, and Sport Discus databases was used to identify SRM led interventions. In sum, 7,169 papers were identified with 360 duplicates. A further 5,122 were removed from title screen, 1,666 from abstract screening, 21 from full text review with two studies included in the final review.

Results
Two SRM led interventions were included in the final review and were deemed as 'fair' quality using Black and Downs Checklist. The first study1 aimed to improve attendance in PE, behaviour and attitude towards PA through a 12-week school based intervention. Schools were funded to complete a novel sport rolled out by teachers (group 1), with a second group having an additional visit from an elite 'athlete mentor' (group 2). The study found 98% of students enjoyed the athlete visits and found them beneficial however there was no additional impact on PE attendance and attitudes to PA linked to athlete visits. The second study2 involved school students visiting a local professional football club and meeting professional football players through video messages and letters over a four-month school period. The intervention group showed a significant increase in self-efficacy towards PA compared to the control group.

Conclusion
There is limited, if any, evidence to support SRM led interventions to promote participation in sport or PA. Studies considered in this review are poorly designed and evaluated and lack theoretical frameworks. There is scope to undertake a broader review of grey literature due to the scarcity of published evidence despite anecdotal support and implementation of SRM

Active ageing
Abstract citation ID: ckac095.055 P04-01 Slovenian approach to healthy and active aging -Fall prevention program for elderly living at home

Issue/problem
Due to the population aging, injuries in relation to falls are a public health problem in Slovenia as well. They are expensive for the health care system, usually have serious consequences and lead to irreversible impairment of function, institutionalization and death. Description of the problem During 2019, registered nurses in community health nursing from 25 Primary Healthcare Centres participated in the MoST pilot project. They conducted a fall risk assessment of 64 years and older patients at their homes, using a Slovenian adaptation of the STEADI (Stopping Elderly Accidents, Deaths & Injuries) questionnaire. At the same time, they also performed an assessment of muscle strength, gait and balance with a timed framed Stand up and go test. Afterwards patients were classified into 3 groups (low, medium, and high risk of falls) and were treated according to the Algorithm for the assessment of the risk of falls for the elderly and prevention measures. Results (effects/changes) 6815 fall risk assessments were conducted (results are preliminary). More details will be presented at the HEPA conference as the data is still being processed. Based on the expected population distribution, mobility and nutrition
